However, even if the performance of the cave dwellers did not satisfy Zhou Tian, it was through their diligence that Zhou Tian obtained a considerable amount of useful information.
Zhou Tian learned from the cave dwellers that there were not many monsters nearby. Apart from them, there were only a few weak demihuman monsters and a large number of NPCs.
Zhou Tian was not sure about the situation in other parts of the continent, but he knew from the cave dwellers that in the area where he was, NPCs were absolutely the strongest force. It could be said that the NPCs now have unified the area where Zhou Tian was. The existence of creatures like the cave dwellers and other Demihuman monsters was not due to the NPCs' lack of ability to wipe them out, but because the NPCs did not need much territory and these monsters posed no threat to them.
If one day these monsters show signs of rising, the NPCs would probably turn around immediately to wipe them out.
